Rather OT, but am I alone in finding the picture above this article creepy?
The two women seem to be pretending to hail a cab, but they aren't making a serious effort to be credible. They're looking away from the traffic on their side of the road, so they're presumably trying to flag down a cab on the opposite side, in which case they need to wave harder. Perhaps the one who's hardly waving at all should stick two fingers in her mouth and whistle?
